"Real-world data continues to reinforce that the presence of STK11m currently result in particularly poor outcomes for NSCLC patients," said Martin Olin, Chief Executive Officer of BerGenBio. "We believe that bemcentinib’s proficiency in blocking AXL overexpression may result in the reversal of an immunosuppressive tumor microenvironment leading to activation of immune response, restoration of sensitivity to immune checkpoint therapy and potentiation of chemotherapy effects in this large, underserved patient population."

Bemcentinib, is a potent, first-in-class highly selective inhibitor of the receptor tyrosine kinase AXL, which is overexpressed in response to cellular stress, inflammation, hypoxia and chemotherapy. STK11 mutations are detected in approximately 20% of non-squamous NSCLC patients and are known to create a more immunosuppressive tumor microenvironment limiting the response to checkpoint inhibition. Preclinical data have demonstrated that by selectively blocking AXL activation, bemcentinib restores sensitivity to immune checkpoint inhibitor therapy, enhances chemotherapy, while also, pertinently, driving the expansion of CD8+ T cells in STK11m models. Early clinical data also point to the activity of bemcentinib in NSCLC patients, including those harboring STK11m.

The global, open-label Phase 1b/2a trial is designed to determine the safety, tolerability and efficacy of bemcentinib with standard of care in untreated advanced/metastatic non-squamous NSCLC patients with STK11 mutations and no actionable mutations. The Phase 1b portion of the study will evaluate the safety and feasibility of bemcentinib in combination with pembrolizumab and doublet chemotherapy in 1L advanced/metastatic non-squamous NSCLC patients, regardless of STK11 status. The Phase 2a expansion part will assess the efficacy of bemcentinib in the same treatment combination in 1L advanced/metastatic non-squamous NSCLC patients with STK11 mutations. The first patient is expected to begin treatment in the fourth quarter of 2022.

Immatics Reports Interim Clinical Data Update on ACTengine® IMA203 TCR-T Monotherapy Targeting PRAME

On October 10, 2022 Immatics N.V. (NASDAQ: IMTX, "Immatics"), a clinical-stage biopharmaceutical company active in the discovery and development of T cell-redirecting cancer immunotherapies, reported a clinical data update for the IMA203 monotherapy covering the completed Phase 1a dose escalation part of the trial and initial data from the first 5 patients in the ongoing Phase 1b dose expansion cohort A (monotherapy) (Press release, Immatics, OCT 10, 2022, View Source [SID1234621881]). In the Phase 1 trial with ACTengine IMA203, Immatics is treating recurrent and/or refractory solid cancer patients utilizing TCR-T cells directed against an HLA-A*02-presented peptide derived from PRAME, which is frequently expressed across several solid cancer indications. Overall, IMA203 continues to be well tolerated and achieved confirmed objective responses across multiple solid cancers such as cutaneous melanoma, ovarian cancer, head and neck cancer, uveal melanoma, and synovial sarcoma. Encouraging early signs of improved durability were seen with a 50% (6/12) confirmed objective response rate, when patients were infused at the target dose or above with more than 1 billion TCR-T cells.

Key clinical findings from IMA203 TCR-T monotherapy
The data obtained during the Phase 1a and Phase 1b cohort A trial provide clinical validation of PRAME as a highly promising T cell target for solid cancers. Confirmed clinical responses were observed at high and low PRAME-expression levels above threshold, indicating IMA203’s potential to provide clinical benefit for all PRAME biomarker-positive cancer patients. The predicted high PRAME prevalence across key indications has so far been supported by prevalence rates obtained during the clinical screening of patients.

Moving from Phase 1a to Phase 1b, Immatics has continued to introduce planned improvements that may influence clinical outcomes including (1) applying higher cell doses (DL4 and exploratory DL5), (2) optimizing the cell product through manufacturing enhancements and (3) working with disease area experts to gradually reduce the fraction of very heavily pre-treated patients with extreme tumor burden who have exhausted standard of care and have undergone multiple clinical trials. In addition, the focus in Phase 1b is also shifting from initial objective response rate (ORR) determined at the ~6-week scan to confirmed ORR determined at the ~12-week scan.

Preliminary Objective Response Rates (ORR; RECIST 1.1) in Phase 1a and Phase 1b Cohort A

1 All patients received >1 billion total TCR-T cells; 2 confirmed ORR (cORR), * 1 patient with SD at ~6-week scan with pending ~12-week scan considered as non-responder for cORR; DL – dose level

Positively evolving durability profile for IMA203 was observed at higher doses: 6 of 12 patients (50%) treated with more than 1 billion infused TCR-T cells (DL4 and DL5) in the Phase 1a and Phase 1b cohort A part of the trial experienced a confirmed objective response (partial response according to RECIST 1.1). In the Phase 1b part of the trial alone, 4 of 5 patients (80%) had a confirmed objective response which were all ongoing at the timepoint of data cut-off.

"The data presented today highlight the clinical potential of PRAME as one of the most promising multi-tumor targets to achieve meaningful benefits for a large cancer patient population," commented Cedrik Britten, MD, Chief Medical Officer at Immatics. "In addition to this first data from IMA203 monotherapy today, we are awaiting data from two additional dose expansion cohorts: IMA203 together with an immune checkpoint inhibitor and our 2nd generation product candidate IMA203CD8. As we continue to shift our focus from Phase 1a to Phase 1b, we look forward to reporting meaningful data throughout 2023, including safety and response rates, as well as durability of response with a longer follow-up time. In addition, we are excited to start a first-in-human trial with our half-life extended Bispecific against PRAME, TCER IMA402, also in 2023."

Safety data for IMA203 monotherapy across Phase 1a and Phase 1b: Treatment with IMA203 continues to show manageable tolerability profile.

At data cut-off on September 6, 2022, 32 patients were infused with IMA203 TCR-T cells.
Most frequent treatment-emergent adverse events (TEAEs) were as expected for cell therapies.
All patients experienced expected cytopenia (Grade 1-4) associated with lymphodepletion. 31 patients (97%) experienced cytokine release syndrome (CRS) of any grade: 29 patients had low to moderate (Grade 1-2), and 2 patients had Grade 3 CRS that occurred in Phase 1a; both recovered to Grade ≤2 after 3 and 4 days. 5 patients (16%) experienced a low to moderate (Grade 1-2) immune effector cell associated neurotoxicity syndrome (ICANS). No dose-dependent increase of CRS and ICANS was observed.
No additional dose limiting toxicities (DLT) were observed since the initial data release in March 2021.
Phase 1a – Clinical activity: IMA203 demonstrated a high initial objective response rate in several solid tumor types.

At data cut-off on September 6, 2022, a total of 27 patients received IMA203 monotherapy in the Phase 1a dose escalation trial:
High initial objective response rate (ORR; partial responses according to RECIST 1.1) of 48% (13/27) was observed at the first CT scan post infusion at ~week 6, and a confirmed ORR of 19% (5/27) the second CT scan at ~week 12.
7 out of 27 patients received doses above 1 billion TCR-T cells (DL4); initial ORR was 57% (4/7) and confirmed ORR was 29% (2/7) in these patients.
Patients were heavily pre-treated with a mean of 4.2 lines of prior systemic treatment and a particularly high baseline tumor burden.
The provisional recommended Phase 2 dose (RP2D) for Phase 1b dose expansion was determined to be DL4.

Phase 1b Cohort A – Clinical activity: IMA203 monotherapy demonstrates high confirmed objective response rate of 80% with early signs of prolonged durability.

At data cut-off on September 6, 2022, 5 patients received IMA203 monotherapy at DL4 and DL5 in the Phase 1b cohort A dose expansion trial:
4 out of 5 patients (80%) experienced an initial objective response at ~week 6 (PR according to RECIST 1.1).
In all 4 patients, objective responses were confirmed at ~week 12 and were ongoing at data cut-off: confirmed ORR was 80% (4/5).
All 4 responses were observed in different solid tumor types: cutaneous melanoma, ovarian cancer, uveal melanoma and head and neck cancer.
Patients were heavily pre-treated with a mean of 4.0 lines of prior systemic treatment and high to moderate baseline tumor burden.

ACTengine IMA203 is currently being evaluated in an ongoing Phase 1b study including three expansion cohorts: (A) IMA203 as a monotherapy, (B) IMA203 in combination with an immune checkpoint inhibitor and (C) IMA203CD8, a next-generation cell therapy where IMA203 engineered T cells are co-transduced with a CD8αβ co-receptor. Further data read-outs on the individual cohorts are planned throughout 2023. In addition to the ACTengine programs, Immatics is addressing PRAME-positive cancers with a second therapeutic modality: TCR Bispecifics. The company’s TCER IMA402 is a next-generation, half-life extended TCR Bispecific which will enter the clinic in 2023. Both approaches, ACTengine and TCER, are distinct therapeutic modalities that have the potential to provide innovative treatment options for a variety of cancer patient populations with different medical needs.

About IMA203 and target PRAME
ACTengine IMA203 T cells are directed against an HLA-A*02-presented peptide derived from preferentially expressed antigen in melanoma (PRAME), a protein frequently expressed in a large variety of solid cancers, thereby supporting the programs’ potential to address a broad cancer patient population. Immatics’ PRAME peptide is present at a high copy number per tumor cell and is homogenously and specifically expressed in tumor tissue. The peptide has been identified and characterized by Immatics’ proprietary mass spectrometry-based target discovery platform XPRESIDENT. Through its proprietary TCR discovery and engineering platform XCEPTOR, Immatics has generated a highly specific T cell receptor (TCR) against this target for its TCR-based cell therapy approach, ACTengine IMA203.

About ACTengine
ACTengine is a personalized cell therapy approach for patients with advanced solid tumors. The patient’s own T cells are genetically engineered to express a novel, proprietary TCR directed against a defined cancer target. The modified T cells are then reinfused into the patient to attack the tumor. The approach is also known as TCR-engineered cell therapy (TCR-T). All Immatics’ ACTengine product candidates can be rapidly manufactured utilizing a proprietary manufacturing process designed to enhance T cell engraftment and persistence in vivo.

The ACTengine T cell products are manufactured at the Evelyn H. Griffin Stem Cell Therapeutics Research Laboratory in collaboration with UTHealth. The ACTengine Programs are co-funded by the Cancer Prevention and Research Institute of Texas (CPRIT).
